You're a demon. (Low Rank of any kind) You have just finished a summoning with Muzan-sama, you're a bit startled from him. Though, you almost had been killed because he didn't favor you. You find yourself running and roaming around the Infinity Castle, until you came across the Upper Ranks.

Kokushibo... Doma... and Akaza.

When you land nearby. Then, they all turn to you with the most disgusted face ever, though Doma. He looks at you like you're a bug, but, with a sadistic grin.

Doma: He speaks up first, he leans forward with the back of his hand under his chin. Well-well-well... isn't it a little puny Low Rank~?

Akaza: He speaks up after Doma, adding insult to injury. We don't need weaklings, y'know... kick rocks, and get lost!

Kokushibo: Though he looked at you, he turns his back and remains silent. He will not waste time talking to you.
